At Netcore email API, we strive to ensure that all of our customers are good senders. We do this by providing guidance on deliverability, best practices for inbox placement, real-time feedback on your sends; and by enforcing policies that protect our sending reputation and the reputation of our customers.

Sender Domain verification is one such policy which helps us to keep your inbox delivery rates high.

Step One: Ownership Verification

One of the crucial steps to start sending emails from Netcore email API is to get your sender domain verified, i.e. confirming that you own the domain.

You can do it by adding our SPF and DKIM records listed under Domain Settings in your Netcore email API account.

At Netcore email API, we are committed to keep the email ecosystem clean and reduce the number of emails landing in spam. To maintain credibility as an email provider and provide our customers with the best deliverability, we follow stringent measures for domain approval. The domain verification process is a combination of programmatic and human checks, which helps us determine if the domain is going to send genuine and relevant emails.

Our delivery team reviews and approves a domain based on multiple factors:

  • Domain ownership
  • Website content
  • Nature of business.
  • List building practices
  • Type of transactional or triggered messages
  • Whether emails are apt to your business
  • Whether the business location matches the location where your account is created and many more.

This whole process of authenticating a domain usually takes less than 2 hours. Once approved and you add your TXT & SPF records, you can start sending emails.

Domain not approved, now what?

If your domain does not get approved, do not panic as that is not the end. If you feel your website ticks off all the conditions above, please do reach out to our support team for a review.

Sometimes the approval process could be delayed. In such cases, we give our best efforts to understand use cases for each domain, and we need a little more information about your website and business. In case we need some clarity, we will contact you on your registered email address. Please do help us with them and your account should get processed quickly.

If you are new to emailing and are stuck with choosing a domain to start with email activity, we give you a few guidelines for the same.

Things to remember when choosing a domain:

A domain is the most crucial part when you start your email activity, be it transactional or promotional. Remember that you do not change the domain name frequently and ensure that it makes a lasting impression on your end-users.

Here we list a few general guidelines to choose a domain:

1. Different name for domain & sub-domain: A completely different domain than your business domain, or a sub-domain of your business domain. Ex: is an entirely different domain, and is a subdomain of your business domain.

2. Different name for Transactional and Promotional sub-domains: In this case, for transactional and for promotional.

3. If you plan to keep your mailing domain separate from your business domain, please make sure that you choose a name that is similar to your business domain and redirect the mailing domain to your business domain. End-user should feel the connectivity between the domains.
